As a noted professional singer in the Midwest, Malley Keelan is an often-requested tenor soloist in churches and funeral homes and special events. Malley is a Lincoln High School graduate, class of 1966, and received his music degree from the University of Nebraska-Lincoln. Earl "Pete" Jenkins was his voice teacher. While there he sang leading tenor roles in opera and oratorio and was active in the Renaissance music ensemble. Another early interest was participation in the famed Pinewood Bowl productions as early as 1963 where he sang leading roles in The Sound of Music, Flower Drum Song and South Pacific between 1964-1977.

Pinafore; Trial by Jury; The Pirates of Penzance and Ruddigore among them.

Under his leadership that ensemble and the Keelan family did over thirty concerts at historic St. Francis Chapel from 1988-1998, raising funds and awareness for its preservation. In 1998 the Lincoln Journal Star in an editorial called the Keelan Family & Friends concerts at the chapel "legendary." With the sale of the chapel that year, the concerts became guests in major churches in Lincoln starting in 1999, notably St. Paul UMC; First Presbyterian; Trinity UMC; First Plymouth UCC; Rosemont Alliance; First UMC. Many celebrated Nebraska artists in music (including Mac McCune; Wilma Sundeen; Betsy Bobenhouse; Tom Trenney), literature (Nebraska poet laurete Bill Kloefkorn and United States poet laurete Ted Kooser) and media have given their time and talents to this annual event to raise funds for a chosen charity and since 2003 Butherus, Maser & Love Funeral Home and Augstum's Printing have been the sponsors.
